Shawnee Mission Park dog park is a 44-acre off-leash area featuring a dog swim area along with a new paved trail to the lake and wood chip and natural surface trails through grassland and wooded areas. The off-leash area also includes paved parking and portable toilets.
The off-leash area is open year-round during regular park hours except during weekly routine maintenance closures (Tuesday and Thursday 5am-9am). Trespassing is prohibited when the gate is locked.
This will be a simple walk to the cache site and should be a simple find at GZ. You will be looking for a cammoed matchstick container. Upped the terrain rating by 1/2 star since you'll have to watch out for dog bombs.
